I cannot help but occasionally loiter in forums that, more than occasionally, showcase writers behaving in less than 100% professional ways. There should be a 12-step group for giving this up. It could rent a room between the groups to help people are addicted to looking at roadkill and the support group for writers who need to break up with a toxic WIP.
Don't know what I am talking about? Try the Amazon Breakthrough Novel Awards Community (in the wake of the cut, especially the threads bitching about the reviewers), and the Lulu forums (pretty much any time, especially the bottom two subforums).
